An airlock is a device which permits the passage of objects, people, and the like, between two drastically different environments, such as between a pressurized and vacuum environment or between an underwater and dry environment. The lock consists of two airtight doors in series which do not open simultaneously, allowing the intermediate chamber to change from one environment to the other.

An airlock is a point of entry aboard a starship or space station which allows ingress and egress into empty space or onto another vessel which has docked at the airlock. The function of an airlock is to create a buffer zone between two areas of differing atmospheric pressure, preventing massive loss of atmosphere in the main part of a vessel by rapid and violent decompression. For example, if someone in an environmental suit needed to exit a ship to preform a maintenance task in the vacuum of space, he or she would enter the airlock and seal it behind them. The atmosphere inside the airlock would be slowly vented out, making the pressure in the airlock equal to that of the outside environment.

Airlock is the name given for any area of a United Nations Space Command ship where one can leave the ship, such as the lifepod or HEV launch area.

Technically, an airlock is a device which permits the passage of people and objects between a pressure vessel and its surroundings while minimizing the change of pressure in the vessel and loss of air from it. The lock consists of a small chamber with two airtight doors in series which do not open simultaneously. Also, some airlocks on ground prevent compression, such as underwater excursions akin to the space compressions.

An airlock may also be used for passage between environments of different gases rather than different pressures, to minimize or prevent the gases from mixing.

Airlocks are used in UNSC spacecraft to prevent pressure loss from exposure to vacuum either due to a hull breach or the deployment of a lifepod or HEV.[1] Halcyon-class Cruisers in particular employ them as redundancy features for survivability during combat with Covenant warships. The UNSC Hopeful also had an airlock large enough to cycle a fleet of dropships simultaneously.[2]

Covenant airlocks feature a force field similar to Jackal Shield Gauntlets that have to be deactivated to allow anything through. It is impervious to any Human projectiles.

From Wookieepedia, the Star Wars wiki.

An airlock was a structure built into most starships and space stations that allowed beings to enter or exit pressurized atmospheres from the vacuum of space, or sometimes, into high pressure ocean depths. A user would enter the pressurized airlock wearing a space suit, and both exits would be sealed. At this point, the airlock could be safely depressurized so the user could exit the craft. Airlocks were sometimes used for executions.
